Barcelona's Montjuïc is a broad shallow hill with a relatively flat top overlooking the harbour, to the southeast of the city centre. The eastern side of the hill is almost a sheer cliff, giving it a commanding view over the city's harbour immediately below. The top of the hill (a height of 173 metres) was the site of several fortifications, the latest of which (the Castell de Montjuïc) remains today.

The Port of Barcelona has a 2000-year history and a great contemporary commercial importance. It is Europe's ninth largest container port, with a trade volume of 2.3 million TEU's in 2006. The port is managed by the Port Authority of Barcelona. Its 7.86 km2 (3 sq mi) are divided into three zones: Port Vell (the Old Port), the commercial port and the logistics port (Barcelona Free Port). The port is undergoing an enlargement that will double its size thanks to diverting the mouth of the Llobregat river 2 km (1¼ mi) to the south.

The Port Vell (old port) area also houses the Maremagnum (a commercial mall), a multiplex cinema, the IMAX Port Vell and an aquarium.
